GAL project aims the study and development of a state-of-the-art methodology for the determination of precise and high-resolution gravity field models.
The key issue is the precise Kinematic Airborne Gravimetry (KAG), with the joint use of most recent techniques and technologies, such as EGNOS, GPS, Galileo and strapdown Inertial Measurement Units (IMUs), and its further integration with GOCE global models.
KAG is in fact the most promising alternative to the very expensive, slow and troublesome terrestrial surveying; it requires the measurement of the gravity field at the local and global scale.

The GAL concept foresees the combination of satellite-derived global gravity models with airborne-derived local models. While the GOCE gradiometric measurements will provide the global gravity model, the airborne EGNOS/GNSS/INS ranging and inertial measurements will provide the local ones.

M. Eulàlia Parés holds a M.Sc. degree in Mathematics from the University of Barcelona (UB) in 2004 and a MSc in Meteorology and Climatology from the University of Barcelona (UB) in 2005. In 2008, she received a Master Degree in Airborne Photogrammetry and Remote Sensing (IG). In the master thesis, she developed a tool for the generation of simulated realistic inertial measurements. The tool is currently integrated in the CTTC’s testbed GEMMA.

At the CTTC, she is a researcher in the IGN department. She is currently working in the development of new positioning algorithms -from GNSS to INS based multi-sensor systems. The key points of the research she is carrying out are the robustness and the reliability of the algorithms.
